NAME
       ppl_lpsol - a PPL-based mixed integer programming problem solver

SYNOPSIS
       ppl_lpsol [OPTION]... [FILE]

DESCRIPTION
       Reads a file in MPS format and attempts solution using the optimization
       algorithms provided by the PPL.

       See the GNU Linear Programming Kit: Reference Manual (Version 4.38) for
       information on the MPS format.

OPTIONS
       -c, --check[=THRESHOLD] checks the obtained results using GLPK;
	      optima  are  checked  with  a  tolerance	of  THRESHOLD (default
	      1e-09);  input data are also perturbed the same way as GLPK does

       -i, --incremental
	      solves the problem incrementally

       -m, --min
	      minimizes the objective function

       -M, --max
	      maximizes the objective function (default)

       -n, --no-optimization
	      checks for satisfiability only

       -r, --no-mip
	      consider integer variables as real variables

       -CSECS, --max-cpu=SECS
	      limits CPU usage to SECS seconds

       -RMB, --max-memory=MB
	      limits memory usage to MB megabytes

       -h, --help
	      prints this help text to stdout

       -oPATH, --output=PATH
	      appends output to PATH

       -e, --enumerate
	      use the (expensive!) enumeration method

       -pM, --pricing=M
	      use pricing method M for simplex (assumes -s); M is an int  from
	      0	 to  2,	 default 0: 0 --> steepest-edge using floating point 1
	      --> steepest-edge using exact arithmetic 2 --> textbook

       -s, --simplex
	      use the simplex method

       -t, --timings
	      prints timings to stderr

       -v, --verbosity=LEVEL
	      sets verbosity level (from 0 to 4, default 3): 0 -->  quiet:  no
	      output except for errors and

	      explicitly required notifications

	      1	 --> solver state only 2 --> state + optimal value 3 --> state
	      + optimal value + optimum location 4 --> lots of output

       -V, --version
	      prints version information to stdout

AVAILABILITY
       The latest version of the Parma Polyhedra Library and all the  documen‐
       tation is available at http://www.cs.unipr.it/ppl/ .

NOTES
       The  options  -CSECS (--max-cpu=SECS) and -t (--timings) are not avail‐
       able on some platforms.
